The National Weather Service forecast is calling for hot and humid air to flow into Iowa this weekend and it could stick around through the middle of next week. The conditions might be uncomfortable for humans and animals and they could potentially pose a problem for corn producers as well. Farmer Dave Rossman from Hartley, in northwest Iowa, says this year has been a mixed bag that started out cold and dry.

Recent rains helped, and usually corn thrives with heat and humidity, but Rossman worries about the heat and wind.

Breezy conditions could offset the humidity.

The most recent U-S-D-A crop report shows both corn and soybeans rated 58-percent, good to excellent, with one-third falling into the fair category. Rossman says his soybeans do have early signs of disease.
